Latent heat of ice is $80 \, cal/g$. $A$ man melts $60 \, g$ of ice by chewing in $1 \, minute$. His power is ........ $W$.

Steam at $100\,^{\circ}C$ is more dangerous than the same mass of water at $100\,^{\circ}C$ because the steam

When boiling water converts into steam,what is the specific heat of water at this state?

What is latent heat? Explain with an example.

$A$ solid cube having certain fixed melting and boiling points takes heat from some source. The variation of temperature $\theta$ of the cube with the heat supplied $Q$ is shown in the adjoining graph. The portion $BC$ of the graph represents the conversion of

Explain the three states of matter and the process of change in states.
